[Bug c++/41412] New: SEGFAULT when declaring two 724 x 724 matrices of doubles in class

[maltusan at gmail dot com]

When two matrices of the type double, sized [724][724] or more are declared, as
private variables of a class, the program crashes as soon as this class
constructor is called. 

724 is the magic number; 723 does not trigger the bug. The type has to be
double also, no other built-in does the job.

The exact version I'm using is Ubuntu 4.3.3-5ubuntu4.

Here's a little source file that triggers the bug:

class foo
{
  double a[724][724], b[724][724];

public:

foo ()
  {
  }
};

int
main ()
{
  foo bar;
}

Oh. I'm sorry. As it didn't happen when I declared the variables outside a
class, I didn't think it was a memory issue.
